A base ball diamond is square.The distance from home plate to first base is 90 feet.what is the distance from home plate to seco
Elena-2011 [213]

Because it is square, the distance from home to first base is the same as first base to second base.


Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.


Using the Pythagorean Theorem we can solve for the hypotenuse:

Let C = the hypotenuse:

90^2 + 90^2 = c^2

8100 + 8100 = c^2

16200 = c^2

c = √16200

c = 127.279 feet, round to 127 feet.

Which of the following is a difference of cubes? x^6 + 27y^9 3x^9 - 64y^3 27x^{15} - 9y^3 125x^{21} - 64y^3
astraxan [27]

Answer:

  • D) 125x²¹- 64y³  

Step-by-step explanation:

  • A) x⁶ + 27y⁹ = (x²)³ + (3y³)³  - sum of cubes
  • B) 3x⁹ - 64y³ - the first term is not a cube
  • C) 27x¹⁵ - 9y³ - the second term is not a cube
  • D) 125x²¹- 64y³ = (5x⁷)³ - (4y)³ - difference of cubes

Correct option is the last one
